Ranolazine
About Ranolazine
Ranolazine is a prescription oral medication primarily used to treat chronic chest pain, also known as angina. It is prescribed for long-term management to help reduce the frequency of chest pain episodes. This medication is not intended to treat sudden, acute attacks of angina.
To work effectively, Ranolazine must be taken consistently every day, usually twice daily, as directed by your doctor. You can take this medication with or without food, but it is important to be consistent with whichever method you choose. Combining this treatment with heart-healthy lifestyle habits, such as eating a balanced diet and engaging in light, doctor-approved physical activity, can significantly improve your overall outcomes.
While taking this medicine, some patients may experience mild side effects like dizziness, headache, nausea, or constipation. If you experience serious symptoms such as an irregular heartbeat, severe lightheadedness, or shortness of breath, you should contact your doctor immediately.
Do not take this if you have moderate to severe liver damage, as your body will not be able to process the medicine safely. Before starting, tell your healthcare provider if you have kidney problems or a family history of heart rhythm issues.
Ranolazine can interact with certain medications, grapefruit juice, and alcohol, which can increase the risk of side effects like dizziness or heart rhythm changes. Pregnant women, breastfeeding mothers, and elderly patients should consult their doctor before starting this medicine to ensure it is safe for their specific circumstances.

Patients Concern
Disease/Condition Glossary
Angina pectoris: Angina pectoris is discomfort in the chest or chest pain that generally occurs due to coronary artery disease (CAD) when an adequate amount of oxygen and blood is not reaching the heart and its muscles. It can also be due to the blockage of the heart's arteries. It helps prevent any further attack of angina by making the heart work more efficiently, but it does not stop an acute attack of angina pectoris.
FAQs
Ranolazine is used alone or with other medicines to treat angina pectoris.
The active substance in Ranolazine is Ranolazine, which reduces sodium ions flow into the heart muscle cells. This interferes with the activity of special channels on the cell surface called sodium-dependent calcium channels through which calcium ions normally enter the cells. This reduces the number of calcium ions that enter the cells. Calcium ions normally cause the heart muscle to contract. By reducing the flow of calcium into the cells, Ranolazine is thought to help the heart to relax, improving blood flow to the heart muscle and relieving the symptoms of angina pectoris.
No, Ranolazine does not stop acute attacks (sudden attacks) of angina, but Ranolazine helps prevent a new attack.
No, alcohol should not be taken with Ranolazine as it may lead to unwanted side effects and increase angina attacks.
Yes, smoking (tobacco) decreases the efficacy of Ranolazine, especially when taken for angina (chest pain), so it should be avoided while taking Ranolazine.
Yes, Ranolazine can cause an upset stomach when taken empty stomach. So, to avoid it, Ranolazine should be taken with a meal for best results.
Yes, Ranolazine can cause drowsiness. If you feel excessively sleepy, please consult your doctor for better advice.
Some major side effects include a rapid, pounding, or irregular heartbeat, difficulty breathing, and fainting. If you encounter any of these symptoms, contact your doctor immediately.
Do not take more than the prescribed dose of Ranolazine as it may cause overdose. The symptoms of overdose include nausea, vomiting, confusion, dizziness, double vision, fainting, difficulty speaking, uncontrollable shaking of a part of the body, hallucinations and burning, pain, numbness, or tingling in any part of the body. If you suspect you have taken overdose or notice signs of overdose, please consult a doctor immediately.
Ranolazine may increase the blood levels and effects of metoprolol. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects.
Ranolazine might raise metformin levels, increasing the risk of lactic acidosis. If you are prescribed ranolazine while taking metformin, discuss it with a healthcare physician. They may offer a lesser dose of metformin as a safer alternative.
You can take it if prescribed by the doctor. However, limit simvastatin to 20 mg once daily in individuals taking any dose of Ranolazine.
No, you should never crush, chew, or split Ranolazine tablets. They are designed as extended-release tablets to slowly release the medicine into your body over time. Breaking them can cause too much medication to be absorbed at once. Talk to your doctor if you have trouble swallowing tablets.
Dizziness is a common side effect, especially when starting the medication. Try to sit or lie down until the feeling passes, and rise slowly when standing up. If the dizziness is severe or does not improve, talk to your doctor.
Unlike many other chronic chest pain medications, Ranolazine does not significantly lower your blood pressure or slow your heart rate. This makes it a useful option for patients who already have low blood pressure or a slow pulse. Talk to your doctor for more details.
No, you should avoid grapefruit and grapefruit juice entirely while taking Ranolazine. Grapefruit blocks enzymes that break down the drug, which can lead to dangerously high levels of the medicine in your body. Talk to your doctor or pharmacist if you have questions about foods to avoid.
Ranolazine starts working within a few days, but it may take several weeks of consistent use to notice a significant reduction in your chest pain episodes. Keep taking it daily even if you do not feel immediate relief. Talk to your doctor if your symptoms do not improve.
The safety of Ranolazine during pregnancy and breastfeeding is not fully established. You should only use this medication if the potential benefit justifies the potential risk. Talk to your doctor to discuss safer alternatives.
